Description
本発明は、表示技術分野に関し、特にディスプレイの画像表示方法、及びディスプレイに関する。 The present invention relates to the field of display technology, and more particularly to a display image display method and a display.
アクティブマトリクス式有機発光ダイオード（以下、ＡＭＯＬＥＤと略称する）は、新世代のディスプレイである。伝統的な画素配列の画素ユニットは、赤、緑、青の３つのサブピクセルからなる。しかし、現在のＡＭＯＬＥＤの画素配列の設計は、サブピクセルの数量を減少する傾向がある。よって、画素配列の個別画素（画素ドットや画素ユニットとも称する）は、赤、緑、青の３つのサブピクセルからなることではない。 An active matrix organic light emitting diode (hereinafter abbreviated as AMOLED) is a new generation display. A pixel unit of a traditional pixel array is composed of three sub-pixels of red, green, and blue. However, current AMOLED pixel array designs tend to reduce the number of subpixels. Therefore, individual pixels (also referred to as pixel dots or pixel units) in the pixel array are not composed of three sub-pixels of red, green, and blue.
図１の画素配列は、Ｄｅｌｔａ配列によるものであり、その行周期が２であり、列周期が３である。当該画素配列の画素は、赤と緑、赤と青、又は、緑と青等の異なる方式によって構成されてもよい。 The pixel array in FIG. 1 is based on the Delta array, and has a row period of 2 and a column period of 3. The pixels in the pixel array may be configured by different methods such as red and green, red and blue, or green and blue.
三原色の場合こそ、すべての色を再現することができることはよく知られており、２種類の色によってはすべての色を再現することが不可能であるため、実際に画像を表示する場合、１つの画素は、それと隣り合う画素から他の１種類の色を「借」用することにより、三原色を構成し、即ち、表示するように画素補償を行う必要がある。 In the case of the three primary colors, it is well known that all colors can be reproduced, and it is impossible to reproduce all colors depending on the two kinds of colors. One pixel needs to perform pixel compensation so as to constitute the three primary colors by “borrowing” one other type of color from the adjacent pixels, that is, display.
従来ディスプレイの表示方法では、使用される画素補償アルゴリズムは、「隣り合う画素の借用方法」であり、即ち、水平方向や垂直方向において、各画素ユニットとそれに隣り合う画素ユニットは、自分自身が備えていない色のサブピクセルを共用して、白色を表示する効果を達成する。「隣り合う画素の借用方法」の具体的なステップは、以下の通りである。 In the conventional display method, the pixel compensation algorithm used is “adjacent pixel borrowing method”, that is, each pixel unit and the pixel unit adjacent to it in the horizontal and vertical directions are provided by itself. The effect of displaying white is achieved by sharing sub-pixels that are not colored. Specific steps of the “adjacent pixel borrowing method” are as follows.
なお、以下の説明において、Ｒ′は、表示待機ピクチャにおけるある画素の実際な階調値であり、Ｒ′′は、Ｄｅｌｔａ画素配列において対応する画素が表示すべき階調値であり、Ｒは、Ｄｅｌｔａ画素配列における最終表示の階調値である。 In the following description, R ′ is an actual gradation value of a certain pixel in the display standby picture, R ″ is a gradation value to be displayed by the corresponding pixel in the Delta pixel array, and R is , The final display gradation value in the Delta pixel array.
図１における画素Ｐｉｘｅｌ（２、２）を例として、当該画素は、Ｇ、Ｂの２種のサブピクセルのみを備え、欠ける赤色Ｒ′（２、２）は、隣り合う左右両方の画素における赤色Ｒ（２、１）及びＲ（２、３）中の０．５ＲＲｅａｌで表示する。 Taking the pixel Pixel (2, 2) in FIG. 1 as an example, the pixel includes only two types of subpixels G and B, and the missing red R ′ (2, 2) is the red color in both adjacent left and right pixels. It is indicated by 0.5R Real in R (2,1) and R (2,3).
Ｒ′′（２、１）＝Ｒ′（２、１）＋１／２Ｒ′（２、２）。
Ｒの面積がＲ′の面積の１．５倍であるため、同じ表示効果を得る場合、Ｒの階調値は、１．５を減少できる。
R ″ (2,1) = R ′ (2,1) + 1 / 2R ′ (2,2).
Since the area of R is 1.5 times the area of R ′, the gradation value of R can be reduced by 1.5 when the same display effect is obtained.
しかしながら、上記補償アルゴリズムに基づく従来技術の表示方法を使用して得られた画像品質は、図２〜図５に示すように、画面エッジがぼんやりし、飽和度が良くないという技術問題が存在する。 However, the image quality obtained by using the conventional display method based on the above compensation algorithm has a technical problem that the screen edge is blurred and the degree of saturation is not good, as shown in FIGS. .
そして、上記補償アルゴリズムを応用する従来技術の表示方法は、例えば、主文字表示を主とする応用や、画像表示を主とする応用などのディプレイ応用の異なる状況を区別・対応できないため、それぞれの満足な表示効果を得られない。 And, since the display method of the prior art applying the above compensation algorithm cannot distinguish / correspond to different situations of display applications such as applications mainly displaying main characters and applications mainly displaying images, respectively, The satisfactory display effect cannot be obtained.
本発明は、従来技術に存在する上記の問題を解消するためになされたものであり、その目的は、ディスプレイの画像表示方法を提供することである。 The present invention has been made to solve the above-described problems existing in the prior art, and an object of the present invention is to provide an image display method for a display.

以下、図８に示すような画素配列を例として、本発明の２つの実施例に係るディスプレイの画像表示方法を説明する。図９は、図８に示すような画素配列の基本画素ユニット３０である。図８に示すような画素配列において、当該画素配列は、行周期が２であり、列周期が３であるｄｅｌｔａ分布の画素配列である。本発明に係るディスプレイの画像表示方法は、ｄｅｌｔａ配列に応用される画素配列に限定されない。他の画素配列方式の画素配列に適用してもよい。 Hereinafter, a display image display method according to two embodiments of the present invention will be described using a pixel array as shown in FIG. 8 as an example. FIG. 9 shows a basic pixel unit 30 having a pixel array as shown in FIG. In the pixel array as shown in FIG. 8, the pixel array is a delta distribution pixel array in which the row period is 2 and the column period is 3. The display image display method according to the present invention is not limited to the pixel array applied to the delta array. You may apply to the pixel arrangement | sequence of another pixel arrangement system.
図８において、第１行のサブピクセルのすべてが赤色のサブピクセルＲであり、第２行のサブピクセルのすべてが青色のサブピクセルＢであり、第３行のサブピクセルのすべてが緑色のサブピクセルＧである。以下、順次に循環する。そして、本発明に係るディスプレイ及び表示方法は、上記の画素配列に限定されない。例えば、第１行のサブピクセルは、緑色のサブピクセル及び青色のサブピクセルであってもよい。 In FIG. 8, all of the subpixels in the first row are red subpixels R, all of the subpixels in the second row are blue subpixels B, and all of the subpixels in the third row are green subpixels. Pixel G. Thereafter, it circulates sequentially. The display and display method according to the present invention are not limited to the above pixel arrangement. For example, the subpixels in the first row may be a green subpixel and a blue subpixel.
図９に示すような画素配列は、実質上、２つのサブピクセルで１つの画素２１０を具現する。図９において、画素２１０を構成する２つのサブピクセルは、楕円形の破線でマークされた。 The pixel arrangement as shown in FIG. 9 substantially implements one pixel 210 with two subpixels. In FIG. 9, the two subpixels constituting the pixel 210 are marked with an elliptical broken line.
図８に示すような画素配列は，複数の図９に示すような基本画素ユニット３０が水平方向、及び垂直方向に沿って繰り返されることによって構成される。各基本画素ユニット３０は、２行３列の６つの画素を含み、具体的には、第１行における左から右に配列される第１の画素Ｐ１１、第２の画素Ｐ１２、及び第３の画素Ｐ１３と、第２行における左から右に配列される第４の画素Ｐ２１、第５の画素Ｐ２２、及び第６の画素Ｐ２３とを含む。ここで、第２の画素Ｐ１２〜第５の画素Ｐ２２は、それぞれ２つの隣り合う水平行に位置する異色のサブピクセルにより構成される。また、第１の画素Ｐ１１と第６の画素Ｐ２３とは、それぞれ同一列に位置するが１つの水平行を間隔する異色のサブピクセルにより構成される。図９から分かるように、画素マトリクスの基本ユニット３０において、赤色のサブピクセルＲ１２、緑色のサブピクセルＧ１３、及び青色のサブピクセルＢ２２は、２つの異なる画素の画素空間にある。 The pixel array as shown in FIG. 8 is configured by repeating a plurality of basic pixel units 30 as shown in FIG. 9 along the horizontal direction and the vertical direction. Each basic pixel unit 30 includes six pixels in two rows and three columns, specifically, a first pixel P11, a second pixel P12, and a third pixel arranged from left to right in the first row. The pixel P13 includes a fourth pixel P21, a fifth pixel P22, and a sixth pixel P23 arranged from left to right in the second row. Here, the second pixel P12 to the fifth pixel P22 are each composed of two adjacent sub-pixels located in parallel with each other. The first pixel P11 and the sixth pixel P23 are each composed of different-colored sub-pixels that are located in the same column but are spaced apart from each other by one horizontal line. As can be seen from FIG. 9, in the basic unit 30 of the pixel matrix, the red sub-pixel R12, the green sub-pixel G13, and the blue sub-pixel B22 are in the pixel space of two different pixels.
図９に示すように、第１の画素Ｐ１１の２つのサブピクセルと第４の画素Ｐ２１の青色のサブピクセルＢ２１とは、垂直方向において第１の間隔をもって上から下に順次に第１列を構成する。 As shown in FIG. 9, the two sub-pixels of the first pixel P11 and the blue sub-pixel B21 of the fourth pixel P21 are arranged in the first column sequentially from top to bottom with a first interval in the vertical direction. Configure.
第２の画素Ｐ１２における青色のサブピクセルＢ１２、第４の画素Ｐ２１における赤色のサブピクセルＲ２１、及び第５の画素Ｐ２２における緑色のサブピクセルＧ２２は、垂直方向において第１の間隔をもって上から下に順次に第２列を構成する。上記第２列と上記第１列とは、水平方向において第２の間隔をもってずらす。基本画素ユニット３０において、図９に示すように、すべて４つのサブピクセル列を有する。 The blue sub-pixel B12 in the second pixel P12, the red sub-pixel R21 in the fourth pixel P21, and the green sub-pixel G22 in the fifth pixel P22 are arranged from top to bottom with a first interval in the vertical direction. The second column is constructed sequentially. The second row and the first row are shifted with a second interval in the horizontal direction. The basic pixel unit 30 has four subpixel columns as shown in FIG.
より具体的には、同一の画素ドットを構成される２つのサブピクセルの間に混色を発生しないように、上記第１の間隔が１つのサブピクセルの高さより小さく、上記第２の間隔が０以上であってもよい。 More specifically, the first interval is smaller than the height of one sub-pixel and the second interval is 0 so that no color mixture occurs between two sub-pixels constituting the same pixel dot. It may be the above.
三原色である場合のみ、すべての色を再現することができるが、２種類の色ではすべての色を再現することが不可能であるため、実際に画像を表示する場合、１つの画素は、他の画素の他の１種類の色を含んで三原色を構成し、協力して白色を表示する効果を達成する。本発明の実施例に係る表示方法は、各色が前記画素において占められる割合、及び当該色が原画像における所在位置及び階調値を算出することにより、画素マトリクスにおける当該色の表示階調値を確定する。 Only when there are three primary colors, all colors can be reproduced. However, since it is impossible to reproduce all colors with two types of colors, one pixel must be displayed when the image is actually displayed. The three primary colors are formed by including one other color of the pixel, and the effect of displaying white in cooperation is achieved. The display method according to the embodiment of the present invention calculates a display gradation value of the color in the pixel matrix by calculating a ratio of each color occupied in the pixel, and a position and a gradation value of the color in the original image. Determine.
第１の実施例
本実施例において、まず、表示待機画像における各色の位置と表示に必要な階調値を表示するデータを獲得する。例えば、赤色の場合、画素Ｐ１１〜Ｐ２３における表示に必要な階調値は、Ｒ′１１、Ｒ′１２、Ｒ′１３、Ｒ′２１、Ｒ′２２、Ｒ′２３であるとする。
First Embodiment In this embodiment, first, data for displaying the position of each color in the display standby image and the gradation value necessary for display is acquired. For example, in the case of red, the gradation values required for display in the pixels P11 to P23 are R′11, R′12, R′13, R′21, R′22, and R′23.
その後、各色のサブピクセルが各画素で占められる割合の割合ベクトルを得り、各割合ベクトルは、赤色のサブピクセル、緑色のサブピクセル、及び青色のサブピクセルのそれぞれが上記画素における割合係数を表示する３つの分量を備える。 After that, we get a ratio vector of the ratio that each color sub-pixel occupies in each pixel, and each ratio vector displays the ratio coefficient in the above-mentioned pixel for each of the red sub-pixel, the green sub-pixel and the blue sub-pixel. It has three quantities to do.
ここで、「割合」とは、占められる空間の割合である。従って、本発明の実施例において使用された補償アルゴリズムは、「占める空間アルゴリズム」と称してもよい。なお、本発明の実施例に係る表示方法において、サブピクセルの画素空間における割合係数を正確に計算する必要がなく、当該画素の画素空間内に当該色のサブピクセルがあるか否かを判断だけである。当該色のサブピクセルの全体が当該画素の画素空間（面積の概念であり、体積の概念ではない）に位置する場合，割合係数が「１」に設定され、当該色のサブピクセルの全体が当該画素の画素空間に位置しない場合、割合係数が「０」に設定され、当該色のサブピクセルの一部が当該画素の画素空間に位置する場合、その大部分が当該画素の画素空間に位置しても、小部分が当該画素の画素空間に位置しても、割合係数が「０．５」に設定される。 Here, the “ratio” is the ratio of the occupied space. Therefore, the compensation algorithm used in the embodiment of the present invention may be referred to as an “occupying spatial algorithm”. In the display method according to the embodiment of the present invention, it is not necessary to accurately calculate the ratio coefficient of the subpixel in the pixel space, and it is only determined whether there is a subpixel of the color in the pixel space of the pixel. It is. When the entire subpixel of the color is located in the pixel space of the pixel (the concept of area, not the concept of volume), the ratio coefficient is set to “1” and the entire subpixel of the color is When the pixel is not located in the pixel space, the ratio coefficient is set to “0”, and when a part of the sub-pixel of the color is located in the pixel space of the pixel, the majority is located in the pixel space of the pixel. However, even if the small portion is located in the pixel space of the pixel, the ratio coefficient is set to “0.5”.
上記から分かるように、図９に示すような基本画素ユニット３０の６つの画素Ｐ１１、Ｐ１２、Ｐ１３、Ｐ２１、Ｐ２２、Ｐ２３の各割合ベクトルは、それぞれ
Ｐ１１（１、１、０）、Ｐ１２（０．５、０．５、１）、Ｐ１３（０．５、０．５、１）
Ｐ２１（０、０、１）、Ｐ２２（１、１、０．５）、Ｐ２３（１、１、０．５）
である。
As can be seen from the above, the ratio vectors of the six pixels P11, P12, P13, P21, P22, P23 of the basic pixel unit 30 as shown in FIG. 9 are P11 (1, 1, 0), P12 (0, respectively). .5, 0.5, 1), P13 (0.5, 0.5, 1)
P21 (0, 0, 1), P22 (1, 1, 0.5), P23 (1, 1, 0.5)
It is.
割合マトリクスを得るように、各上記割合ベクトルにおける同一位置の分量をそれぞれ取る。割合マトリクスは、各色の上記画素配列における各画素に占められた空間割合のデータを表示する。従って、次式が得られる。即ち、 In order to obtain a ratio matrix, the amount of the same position in each ratio vector is taken. The ratio matrix displays data of the space ratio occupied by each pixel in the pixel array of each color. Therefore, the following equation is obtained. That is,
割合マトリクスを獲得した後、上記基本画素ユニット３０内の各サブピクセルに対しては、当該サブピクセルが存在する画素の表示に必要な階調値に、上記割合マトリクスにおいて対応するマトリクス要素値をそれぞれかけて、当該サブピクセルの上記画素配列における表示階調値を獲得する。具体的には、以下の通りである。 After obtaining the ratio matrix, for each sub-pixel in the basic pixel unit 30, the corresponding matrix element value in the ratio matrix is set to the gradation value necessary for displaying the pixel in which the sub-pixel exists. As a result, the display gradation value in the pixel array of the subpixel is obtained. Specifically, it is as follows.
Ｒ１１＝Ｒ′１１；Ｒ１２＝０．５Ｒ′１２＋０．５Ｒ′１３
Ｒ２１＝Ｒ′２２；Ｒ２３＝Ｒ′２３
Ｇ１１＝Ｇ′１１；Ｇ１３＝０．５Ｇ′１２＋０．５Ｇ′１３
Ｇ２２＝Ｇ′２２；Ｇ２３＝Ｇ′２３
Ｂ１２＝Ｂ′１２；Ｂ１３＝Ｂ′１３
Ｂ２１＝Ｂ′２１；Ｂ２２＝０．５Ｂ′２２＋０．５Ｂ′２３
上記各公式において、Ｒは、画素配列における赤色が存在する位置及び階調値であり、Ｒ′は、原画像における赤色が存在する位置及び階調値であり、Ｇは、画素配列における緑色が存在する位置及び階調値であり、Ｇ′は、原画像における緑色が存在位置及び階調値であり、Ｂは、画素配列における青色が存在する位置及び階調値であり、Ｂ′は、原画像における青色が存在する位置及び階調値である。
R11 = R′11; R12 = 0.5R′12 + 0.5R′13
R21 = R'22; R23 = R'23
G11 = G′11; G13 = 0.5G′12 + 0.5G′13
G22 = G′22; G23 = G′23
B12 = B′12; B13 = B′13
B21 = B'21; B22 = 0.5B'22 + 0.5B'23
In the above formulas, R is the position and gradation value where red exists in the pixel array, R ′ is the position and gradation value where red exists in the original image, and G is the green position in the pixel array. G ′ is the position and gradation value where green is present in the original image, B is the position and gradation value where blue is present in the pixel array, and B ′ is This is the position and gradation value where blue color exists in the original image.
第２の実施例
本実施例の上記実施例と同じ部分は贅言しない。
Second Embodiment The same part as the above embodiment of the present embodiment is not exaggerated.
本実施例と上記実施例との異なることは、本実施例の表示方法においても、当該画素の画素空間の百分率を正確に計算する必要なく、当該画素の画素空間内に当該色のサブピクセルがあるか否かを判断する。当該色のサブピクセルの全体当該画素の画素空間（面積の概念であり、体積の概念ではない）に位置する場合、割合係数が「１」に設定され、当該色のサブピクセルの全体が当該画素の画素空間に位置しない場合、割合係数が「０」に設定され、当該色のサブピクセルの一部が当該画素の画素空間に位置する場合、その大部分が当該画素の画素空間に位置するか、それとも小部分が当該画素の画素空間に位置するかを判断必要があり、その大部分が当該画素の画素空間に位置する場合、割合係数が０．５より大きい「０．７」に設定されてもよく、小部分が当該画素の画素空間に位置する場合、割合係数が０．５より小さい「０．３」に設定されてもよい。つまり、両者の和は、１である。 The difference between this embodiment and the above embodiment is that, even in the display method of this embodiment, it is not necessary to accurately calculate the percentage of the pixel space of the pixel, and the subpixel of the color is in the pixel space of the pixel. Judge whether there is. When the entire subpixel of the color is located in the pixel space of the pixel (the concept of area, not the concept of volume), the ratio coefficient is set to “1”, and the entire subpixel of the color is the pixel If the pixel is not located in the pixel space, the ratio coefficient is set to “0”, and if some of the sub-pixels of the color are located in the pixel space of the pixel, are most of them located in the pixel space of the pixel? It is necessary to determine whether or not a small part is located in the pixel space of the pixel, and when the majority is located in the pixel space of the pixel, the ratio coefficient is set to “0.7” which is larger than 0.5. Alternatively, when the small portion is located in the pixel space of the pixel, the ratio coefficient may be set to “0.3” smaller than 0.5. That is, the sum of the two is 1.
上記から分かるように、本実施例において、図９に示す基本画素ユニット３０の６つの画素のように、その赤、緑、青のサブピクセルが各画素で占められる割合の割合ベクトルは、それぞれ
Ｐ１１（１，１，０）、Ｐ１２（０．７，０．７，１）、Ｐ１３（０．３，０．３，１）
Ｐ２１（０，０，１）、Ｐ２２（１，１，０．７）、Ｐ２３（１，１，０．３）

次に、本発明の２つの実施例に係る表示方法のいくつか具体的な画像の表示状況をさらに説明する。 Next, some specific image display states of the display method according to the two embodiments of the present invention will be further described.
まず、第２の実施例に係る表示方法により図１０に示すような画像を表示することを例に挙げて説明する。図１０の画像において、枠線の幅は、３つの画素であり、内部の横線の幅は、１〜７つの画素で増加するように構成され、内部の縦線の幅も１〜７つの画素で増加するように構成される。画像面積を考慮して、図１１〜図１３は、図１０に示すような画像の画素効果図の一部を示す図である。図１３に示すように、その中の１列の低階調レベルのサブピクセル列は、表示できない。図１０の画像は、赤色で表示するが、本発明がそれに限定しない。青色や、緑色で表示する場合、同じ効果を有する。ここでは赤色を例に挙げて説明する。 First, an example of displaying an image as shown in FIG. 10 by the display method according to the second embodiment will be described. In the image of FIG. 10, the width of the frame line is 3 pixels, the width of the internal horizontal line is increased by 1 to 7 pixels, and the width of the internal vertical line is also 1 to 7 pixels. Configured to increase at. In consideration of the image area, FIGS. 11 to 13 are diagrams showing a part of the pixel effect diagram of the image as shown in FIG. As shown in FIG. 13, one of the low gradation level sub-pixel columns cannot be displayed. Although the image of FIG. 10 is displayed in red, the present invention is not limited to this. When displaying in blue or green, it has the same effect. Here, red will be described as an example.
図１１〜図１３に示すように、本発明の第２の実施例に係る表示方法を使用して表示する場合、線の幅が１つの画素である縦線は、３種類の表示方法を有する。図９に示すような画素配列の横方向の画素の周期が３つの列であるため、３種類の異なる縦線を表示できる。３種類の異なる縦線は、赤色のサブピクセルを例に挙げて、それぞれ図１４〜図１６に示される。 As shown in FIGS. 11 to 13, when displaying using the display method according to the second embodiment of the present invention, a vertical line having a line width of one pixel has three kinds of display methods. . Since the period of the pixels in the horizontal direction of the pixel array as shown in FIG. 9 is three columns, three different vertical lines can be displayed. Three different types of vertical lines are shown in FIGS. 14 to 16, taking a red sub-pixel as an example.
図１４に示すように、第１種の縦線が表示される場合、１つの赤色のサブピクセル列のみで表示するとともに、１行を間隔して１つの赤色のサブピクセルを点灯し、表示に必要な赤色の階調値の１００％で表示する。 As shown in FIG. 14, when the first type of vertical line is displayed, only one red sub-pixel column is displayed, and one red sub-pixel is turned on at intervals of one row. Display with 100% of the required red gradation value.
図１５に示すように、第２種の縦線が表示される場合、２つの赤色のサブピクセル列でそれぞれ表示し、ここで、１列の赤色のサブピクセルは、表示に必要な赤色の階調値の１００％で表示し、他の１列の赤色のサブピクセル（図の左から第３列）は、第２の実施例に係る表示方法により表示に必要な赤色の階調値の７０％で表示し、即ち、実際に表示する階調値は、原画像における赤色の階調値の０．７倍である。 As shown in FIG. 15, when the second type of vertical line is displayed, it is displayed in two red sub-pixel columns, where one red sub-pixel is a red floor required for display. Displayed at 100% of the tone value, and another row of red sub-pixels (third column from the left in the figure) has a red tone value of 70 required for display by the display method according to the second embodiment. The gradation value displayed in%, that is, actually displayed is 0.7 times the red gradation value in the original image.
図１６に示すように、第３種の縦線が表示される場合、２つの赤色のサブピクセル列でそれぞれ表示し、ここで、１列の赤色のサブピクセルは、表示に必要な赤色の階調値の１００％で表示し、他の１列のサブピクセル（図の左から第３列）は、第２の実施例に係る表示方法により表示も必要な赤色の階調値の３０％で表示し、即ち、実際に表示する階調値は、原画像における赤色の階調値の０．３倍である。 As shown in FIG. 16, when a third type of vertical line is displayed, it is displayed in two red sub-pixel columns, where one red sub-pixel is a red floor required for display. Displayed with 100% of the tone value, the other one row of subpixels (third column from the left in the figure) is 30% of the red tone value that also needs to be displayed by the display method according to the second embodiment. The gradation value that is displayed, that is, actually displayed is 0.3 times the gradation value of red in the original image.
１つの画素の幅の横線を表示する場合、２つの異なる表示方式のみがある。２種類の表示方式はすべてが同一のサブピクセル行で表示するが、他の幅の横線を表示する場合、実際に発光するサブピクセルの行数が当該横方向の線に含まれる画素の個数に等しい。例えば、表示幅が４つの画素の横線であれば、実際に発光するサブピクセルが４行である。縦線を表示する場合、実際に発光するサブピクセルの行数は、多くの場合、当該縦線の幅に含まれる画素の個数に等しくない。 When displaying a horizontal line with the width of one pixel, there are only two different display methods. The two display methods are all displayed in the same sub-pixel row, but when displaying horizontal lines of other widths, the number of rows of sub-pixels that actually emit light is the number of pixels included in the horizontal line. equal. For example, if the display width is a horizontal line of four pixels, the subpixels that actually emit light are four rows. When displaying a vertical line, the number of rows of subpixels that actually emit light is often not equal to the number of pixels included in the width of the vertical line.
以上、本発明の第２の実施例に係る表示方法による表示線の例を説明したが、以下、本発明の第１の実施例に係る表示方法による表示矢印の例をさらに説明する。 The example of the display line by the display method according to the second embodiment of the present invention has been described above. Hereinafter, the example of the display arrow by the display method according to the first embodiment of the present invention will be further described.
図１７に示すように、図９に示すような画素配列が本発明の第１の実施例に係る表示方法を応用して緑色の矢印を表示する場合、矢印が覆う領域の大部分の緑色のサブピクセルは、表示に必要な緑色の階調値の１００％で表示し、ある境界の場合、緑色のサブピクセルは、表示に必要な赤色の階調値の５０％で表示する。ここで、第１行第１列の画素における緑色のサブピクセルＧ０１０１、第７行第７列の画素における緑色のサブピクセルＧ０７０７、第５行第１６列の画素における緑色のサブピクセルＧ０５１６を含む。 As shown in FIG. 17, when the pixel array as shown in FIG. 9 applies the display method according to the first embodiment of the present invention to display a green arrow, most of the area covered by the arrow is green. The sub-pixel is displayed with 100% of the green gradation value required for display, and in the case of a certain boundary, the green sub-pixel is displayed with 50% of the red gradation value required for display. Here, a green subpixel G0101 in the pixel in the first row and the first column, a green subpixel G0707 in the pixel in the seventh row and the seventh column, and a green subpixel G0516 in the pixel in the fifth row and the 16th column are included.
